Definition: Quattro Pro
A Windows spreadsheet from Alludo (formerly Corel) that provides advanced graphics and presentation capabilities, including goal seeking, 3D graphing and the ability to create multi-layered slide shows. It is optionally keystroke compatible with Lotus 1-2-3. Quattro Pro was originally developed by Borland, then purchased by Novell in 1994 and Corel in 1996. Initially sold as a separate program, Quattro Pro was later added to Corel's WordPerfect Office suites.
